To all whom it may concern.-

Be it known that I, WILLY CARL ZIMMER- MANN, merchant, a subject of theKing of Prussia,Germau Emperor, residingat 12 Burg strasse,Diiren,Gei-mauy,ha ve invented a new and useful Improvement in WeatherStrips, of which the following is a specification.

My present invention concerns a contrivance which has the object ofclosing the space or slit between the loweredge of the door and thefloor, which generally exists when the door is closed.

In the accompanying drawings, Figure 1 represents a longitudinalsection; Fig. 2, a cross-section with the strip below; Fig. 3 across-section with the strip raised The known closing -off elastic stripa is grasped by a number of short spring-clamps b. The strip oi maytherefore be fixed in a slanting position corresponding to theunevenness of the floor or sill. The sides of the clamp run parallel intheir lower part and diverge in the upper part, so that a wedge-likecross-section is formed. The connecting top portion of the clamps isstraight and has a flat spring (1 fastened on it. These clamps b, withthe strip a grasped by them, are pushed into a lining plate (2 for thewedge shaped opening in partf, which carries the weatherstrip. Thelining-plate e is made of plateiron fastened in wooden bars f, havingparallel sides which are fixed in a suitable small groove 9 in the loweredge of a door. The springs cl press the clamps always down, each onefor itself, so that the elastic strip a adapts itself to all unevennessof the floor under the door, and thus a tight closing is obtained.Neither does a bending or sinking of the door prevent the contrivanceworking, as the short clamps are'not influenced by a bendingof thelining-plate e, and by the slightest raising of the elastic strip a theybecome free in their wedge-like parts from the said lining-plate e.

The clamps b can be fastened to the strip a by rivets; still thedescribed arrangement of the claws 0 will be the most advantageous;

The contrivance may not only be applied to the lower edge of a door, butcan be applied to so called wind screens or folding doors for securelyclosing the side or middle clamps, springs fastened on the top of eachclamp, a wedge-shaped lining-plate support ing the mentioned clamps, allas and for the purpose set forth. v

2. The combination with a door provided at its bottom edge with agroove, wooden bars in the groove, a furrow in cross-section wedgeshapedin its upper part and with parallel sides in its lower part, alining-plate in the furrow, wedge-shaped clamps provided with clampsgraspingthe elastic strip, springs fixed to the top of the clamps movingwithin said lining-plate, all as described and for the purpose setforth.

3. A device of the class described comprising a movable weather-stripconsisting of av flexible strip, a number of small clamps grasping theflexible strip by means of claws, a spring on the top of each clamp,wooden bars forming a furrow wedge-shaped in cross-section in a grooveof the bottom edge of a door, and a lining-plate in said furrow, all asand for the purpose set forth.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
